We have one guy who is working on a rewrite of the code on the
experiences we have had with the mobility parts of the code. This
problem is on the list also :)

the current mobility code has been bug fixed multiple times and now it
is time to reorganize the inflated code. Baris is also working on to
support fault-tolerance better in the current mobility code. Fault
tolerance means that daemon will detect problems in connectivity with
ICMPv6 messages to HITs and will try to recover automatically. The
daemon will send UPDATE messages through all possible address pairs to
find even a single working locator pair. A similar procedure will be
applied to base exchange (I1 packets) as well. I would expect
incrementally mergeable results throughout this Spring. Stay tuned!
